Grant County Airport serves Petersburg, West Virginia at 963 ft elevation with its longest runway, 13/31, at 5,000 by 75 ft. The figures below are computed from FAA NASR runway data (via OurAirports) and the same rules of thumb JetDesk uses on the airport page in the app; the POH and current NOTAMs are the authority.

02Density altitude and turboprop runway margins

Standard temperature at 963 ft is about 13°C. Every 1,000 ft of density altitude adds roughly 8 percent to a turboprop's takeoff distance and 5 percent to its landing distance. The table uses Piper Meridian book numbers (2,438 ft takeoff and 2,110 ft landing over a 50 ft obstacle at sea level, ISA, max weight) as a reference airplane; heavier turboprops and light jets scale the same way from their own POH figures.

Conditions	Density altitude	Takeoff est.	Landing est.	Landing × 1.5
Standard day (ISA, 13°C)	963 ft	2,626 ft	2,212 ft	3,317 ft
Warm day (ISA +10)	2,163 ft	2,860 ft	2,338 ft	3,507 ft
Hot day (ISA +20)	3,363 ft	3,094 ft	2,465 ft	3,697 ft
35°C afternoon	3,594 ft	3,139 ft	2,489 ft	3,734 ft

Planning aid only. Even on a 35°C afternoon the longest runway (13/31, 5,000 ft) covers a Meridian-class turboprop's landing distance with a 50 percent margin (3,734 ft needed). The percentages are a generic rule of thumb applied to one reference airplane, not certified performance data for any specific aircraft, and the runway size categories describe the runway, not your airplane's suitability. Verify with the approved flight manual before every flight.

03Nearby fields with 5,000 ft or more
